Abstract

Disclosed is a wet/dry carpet cleaner having a large tank assembly for fluids. A bladder containing fresh or cleaning water is positioned in the large tank. Means for dispensing the cleaning water to a brush, and then vacuuming the same and returning the soiled fluid to the recovery tank portion of the tank assembly are also provided. The present invention stems from the development of a brush head assembly which is pivotally secured to the chassis assembly and includes the driving motor, rotating brush, and spray mechanism. The pivotal securement results in the weight of the brush head assembly applying a constant force on the brush throughout the entire cleaning cycle, independent of the amount of fluid contained in the recovery tank or the bladder. Secondarily, the present invention is addressed to configurating and proportioning the bladder to insure a relatively constant load on the nozzle. By balancing the nozzle loading and, therefore, the downward pressure per square inch on the nozzle throughout the cycle to compensate for fluid loss or fluid re-distribution; with the brush loading remaining constant throughout the cycle, consistency is maintained during the entire period while the carpet is being cleaned.
